Exactly. it's not fair in the sense that platform pricing is not set by an "efficient free market". What you pay for is not the features, it's the visibility. So the pricing of gumroad/apple store/etc is way above their operating costs.

I'd look at it differently: currently running a business, me and my wife are spending a lot more than 30% of our time on non-core activities. If a service would reliably take a chunk of that off of our shoulders, it would absolutely be worth the commission. Especially since there are no fixed costs, no income = no costs.

Thanks for engaging my question.

I now realize I should have been asking if 30% is "reasonable".

For you, absolutely, and I appreciate your explanations.
